Description

Technical Field

[0001] The utility model relates to the technical field of material distribution of an emulsion explosive steel belt cooler, in particular to an automatic material distribution device of an emulsion explosive steel belt cooler. Background Art

[0002] The development trend of the civil explosives industry and the requirement of the competent authorities are to reduce the number of people or even make the production line of emulsion explosives unmanned. At present, the production line of emulsion explosives is divided into water-oil phase configuration workshop, pharmaceutical loading workshop, packaging workshop and transfer platform, all of which belong to Class 1.1 dangerous workshops. The water phase and oil phase configured in the pharmaceutical loading workshop are transported to the rough emulsifier by water phase pump and oil phase pump for emulsification, and then transported to the fine emulsifier by piston electric cylinder pump for fine emulsification. After fine emulsification, it is transported to the steel belt cooler through pipeline for cooling and cooling. After reaching the temperature required by the process, it is sensitized and then pumped to the charging machine for charging. However, when the latex matrix is ​​transported to the steel belt cooler, it needs to be evenly distributed on the steel belt through a distributor to achieve a good cooling effect. Due to the different production capacities of emulsion explosives of different specifications, the larger the capacity, the thicker the corresponding cloth thickness. It is necessary to manually adjust the distance from the cloth roller in the distributor to the surface of the steel belt so that the thickness of the latex matrix on the steel belt is within the range of process requirements. However, this increases the number of staff in the workshop, which does not meet the development trend of the civil explosives industry and the requirements of the competent authorities. The explosives production line must achieve continuous, automated production and safe production, making the automatic cloth function of the steel belt cooler of the emulsion explosive production line particularly important.

[0026] In order to explain the technical content, achieved objectives and effects of the present invention in detail, the following is an explanation in conjunction with the implementation modes and the accompanying drawings.

[0027] Please refer to Figure 1 The specific implementation of the utility model relates to an automatic feeding device for an emulsion explosive steel belt cooler, comprising:

[0028] Cooling machine rack 1;

[0029] A conveyor steel belt 2, wherein the conveyor steel belt 2 is rotatably connected to the cooling machine frame 1, and the conveying direction of the conveyor steel belt 2 is an X direction;

[0030] A cloth adjustment mechanism, the cloth adjustment mechanism comprises a cloth roller 3 and a lifting mechanism 4; the cloth roller 3 is arranged above the conveyor steel belt 2 in a liftable manner, and the axial direction of the cloth roller 3 is the Y direction; the lifting mechanism 4 is connected to the cooling machine frame 1, the cloth roller 3 is connected to the lifting mechanism 4, and the lifting mechanism 4 is used to drive the cloth roller 3 to move up and down;

[0031] A laser distance sensor 5, wherein the laser distance sensor 5 is connected to the cooling machine frame 1, the detection head of the laser distance sensor 5 is downwardly directed toward the surface of the conveyor steel belt 2, and the laser distance sensor 5 is located in the X direction of the cloth adjustment mechanism;

[0032] PLC, the PLC is electrically connected to the laser distance sensor 5 and the lifting mechanism 4 respectively.

[0033] In the above embodiment, the conveyor steel belt 2 is made of 304 stainless steel, has a width of 1200 mm, and a cooling length of 12000 mm; a 304 stainless steel hood is also provided on the cooling machine frame 1, which is distributed around the conveyor steel belt 2 and plays a protective supporting role.

[0034] As a preferred implementation, the number of the cloth adjusting mechanisms is more than 2, and the cloth adjusting mechanisms are arranged and distributed along the X direction.

[0035] As a preferred embodiment, the lifting mechanism 4 includes a vertical screw rod 41, a nut lifting block 42 and a driving member. The vertical screw rod 41 is rotatably connected to the base, and the two vertical screw rods 41 are symmetrically distributed on both sides of the conveyor steel belt 2. The nut lifting block 42 is threadedly connected to the screw rod, and the two ends of the cloth roller 3 are respectively connected to the nut lifting block 42 through bearings. The driving member is connected to the screw rod for driving the screw rod to rotate.

[0036] As a preferred embodiment, a proximity switch 6 is connected to one side of the cooling machine frame 1, and the proximity switch 6 is electrically connected to the PLC. The nut lifting block 42 is provided with a steel plate 421 extending outward. When the nut lifting block 42 drives the cloth roller 3 to descend close to the surface of the conveyor steel belt 2, the proximity switch 6 approaches the steel plate 421 to trigger a signal. For example, when the distance between the surface of the cloth roller 3 and the surface of the conveyor steel belt 2 is 2 mm, the proximity switch 6 just senses the steel plate 421, and by sending a signal to the PLC, the PLC controls the lifting mechanism 4 to stop, thereby playing a protective role in the automatic cloth device.

[0037] In the above embodiment, the steel plate 421 is made of 304 stainless steel, 30 mm long, 10 mm wide and 2 mm thick.

[0038] As a preferred embodiment, in the lifting mechanism 4 , the vertical screw rods 41 on both sides are also transmission-connected with horizontal screw rods 43 , and the driving member includes a motor 44 , which is transmission-connected with the horizontal screw rods 43 .

[0039] As a preferred embodiment, the material of the cloth roller 3 is nylon, with a diameter of 120 mm and a length of 1100 mm.

[0040] As a preferred embodiment, the distance between the detection head of the laser distance sensor 5 and the surface of the conveyor belt 2 is 100 mm. The distance from the center of the laser distance sensor 5 to the side of the conveyor belt 2 is 600 mm.

[0041] The working process of the above embodiment is as follows: the latex matrix is ​​transported to the front end surface of the conveyor steel belt 2 through a pipeline, and the latex matrix is ​​evenly distributed on the surface of the conveyor steel belt 2 through two-stage feeding rollers 3. The laser distance sensor 5 measures the distance from the latex matrix on the surface of the conveyor steel belt 2 to the detection head of the laser distance sensor 5, and transmits it to the PLC data module, and compares it with the distance from the detection head to the surface of the conveyor steel belt 2. The distance difference between the two is the thickness of the latex matrix on the steel belt. When the thickness of the latex matrix deviates from the thickness set by the corresponding production capacity, the control motor 44 drives the horizontal screw 43 to rotate, and then drives the two vertical screws 41 to rotate synchronously, drives the nut lifting block 42 to move upward or downward, thereby driving the feeding roller 3 to move upward or downward. When the thickness of the latex matrix on the conveyor steel belt 2 reaches the set range value, the control motor 44 stops working, and the feeding roller 3 also stops moving upward or downward, thereby controlling the thickness of the latex matrix on the conveyor steel belt 2, and realizing automatic feeding of the emulsion explosive steel belt cooler. When the laser distance sensor 5 fails and the proximity switch 6 senses the steel plate 421, it is transmitted to the PLC data module, and the motor 44 stops working immediately, that is, the cloth roller 3 stops moving downward, avoiding the cloth roller 3 from colliding with the conveyor belt 2, thereby protecting the automatic cloth device.

[0042] The above description is only an embodiment of the present invention, and does not limit the patent scope of the present invention. Any equivalent transformations made using the contents of the specification and drawings of the present invention, or directly or indirectly applied in the relevant technical field, are also included in the patent protection scope of the present invention.
